Try setting up your audio from the beginning - I dont know your computer set up ( desk top with add-on speakers or laptop with built in speakers or your OS ) So I will give you a general example using :-
Laptop with built in mic x webcam with built in mic x Vista OS x Yahoo Messenger

If you have an earlier OS, you may have to access some of your hardware ( speakers and mic ) from the Control Panel.

Hi I am Vortash it sounds to me that this is linked to the realtek program off shutting off the speakers when the earphones are attatched , it is confusing the Mic plug on one channel as a speaker plug .. check in the advanced section of your mixer settings that you have not got the box ticked that says treat all inputs the same .. and the other that says mute rear when front plugged in ? as does mine .. ( same system that was my problem yours may be diffrent ) if this fails uninstall your realtek drivers and uncheck the realtek devices in device manager unistall them and rebboot the computer installing new drivers .. hope this helps regards Vortash

I had the same issue. This is what I found. It seems the Realtek audio and the Microsoft volume drivers are conflicting with each other. If you look at the bottom right (next to clock) you should see the usual grey speaker icon (Microsoft Master Volume controller) and you may also see a reddish speaker (Realtek audio) icon. This should indicate that both are controlling your audio.

If you click [start] - [run], type: msconfig and click [ok]. Click on [startup] tab at top. Look under startup item and uncheck: RTHDCPL then [apply], [ok] and restart your netbook. After it reboots the only audio icon that should appear is the grey speaker (microsoft master volume controller). Your mic should work now. Go to sound recorder and test. You may also need to upgrade to the lasted audio driver from the acer site but try shutting down Realtek first.

Sounds like he forgot to plug back in the sound cable when he took his iPod out. Simple fix for this. Pull out the desktop box (computer) and find what should be a green sound cable and plug it into a green port in the back of your computer. If your having trouble as to what it looks like, get your son to identify what he took out of your desktop to listen to his iPod and plug it back in. Also check that your speakers are turned on and are up on the speakers and on your desktop, which you can find in the bottom right hand corner near your desktop clock. The icon looks like a speaker and just click on it once and make sure its up all the way and not muted. Let me know if this works or not

Hope This Helps

its possible your mic is on mute so no sound gets throught.
check the speaker icon next to your clock

if you dont see microphone there then click on properties and settings and then on playback. Then make sure the microphone has a X next to it below.

then press ok and check settings

also
press settings and then properties and click on recording. then ok. then make sure the microphone is not muted and the sound level is high enought.
